Referring to the drawings, a humidifying device is illustrated shown as a unit having an end member 10. While this member might be varied in shape, in the embodiment of the invention illustrated it is shown as substantially conical in shape having a cen- 39- [device applied tral hub 10a at its apex which is bored to receive a nozzle 11 secured in said hub by the nut 12, and by means of which it is also connected to a liquid supply pipe 13 which will extend to a suitable source of water, either heated or at ordinary temperatures. Nozzle 11 has a discharge portion 11a which is constructed and arranged to project liquid in very finely divided condition. Member 10 adjacent the end opposite hub 10a has a projecting disk-like flange 106 provided with circumferentially spaced holes adapted to receive attaching bolts to secure the humidifying unit in place. Said member 10 has at its inner side a depending comparatively sharp-edged lip 10d adapted to form a drip edge.v Anannular member 14 made of thin sheet material is disposed adjacent member 10 and has a projecting fim or flange 14a disposed in one plane, which flange is provided with a plurality of cireumferentially spaced holes through which pass headed bolts 15. These bolts pass through spacing sleeves 16 engaging the upper sides of the disk portions 14a and a lower flat surface on member 10 between the drip edge 10d and the flange 10?). Member 14 has its outer edge turned upward slightly at a right angle a short distance outward from sleeve 16. A portion of member 14 within the flange 14a is of frusto-' conical shape and has its small end directeddownwardly. A plurality of annular members 17 of sheet material are provided, which members are of frusto-conical shape having their smaller ends directeddownwardly, and said members decrease successively in diameter away fromrthe member 14. Said memhere are connected together and the upper orie thereof is connected to member l4jby headed rivets 18 spaced circumferentiall-y thereabout, said rivets passing through spacing sleeves 19 disposed between said niembers l7 and between the upper one thereof and member 14, which sleeves abut the conical surface of said members and extend substantially at right angles to said conical surfaces. A cup-like member 20 is secured to the lower one of members 17 also by the rivets 18 and the spacing sleeves 19-, said member 20 being substantially of conical shape and having a small opening 20a at its lower end surrounded by a short cylindrical portion. A clip or supporting bracket 21 is formed from a strip of material, the ends of which are disposed along the bottom of member 20 at opposite sides thereof and are secured to said member by the rivets 22. The bight portion of member 21 surrounds and supports a T member 23 having a vertical opening disposed coaxially with opening 20a. A short pipe section 24 extends from one end of T member 23 and another pipe section 25' is secured to the other end of T member 23. Member 25 has threaded thereon at its other end another T member 26 similar to T member 23 and member 26 has its stem opening turned downwardly, the same having secured therein a drain pipe 27. A rod 28 is provided, substantially of the diameter of the bore of pipes 24 and 25 and T member 23 which is adapted to constitute a clean-out instrument, the same being bent at its end to form a ring handle 28a.

In Figs. 4 and 5 a furnace is shown comprising an outer casing 30, an inner easing 31in which is disposed the fire pot and which communicates with a casing 31a through which the products of combustion pass to a smoke pipe 33. lVhile the invention is applicable to any kind of furnace.

the particular furnace shown is of the hotair type, and hashot-air conduits 32 leading from the upper chamber 30a thereof. Casing30has-a"top 3011 which is provided with an opening through which projects theunit shown in Fig. 1, the same having itsfla-ngelObresting on the top of the furnace top 30b'and secured theretoby screws or bolts passing through the holes 100; 'The portion of the humidifying unit belowflange projects through the top of the furnace into chamber 30a as clearly shown, and thedrain pipe 25 extends through'the casing 30 of the furnace, the T member 26 being disposed'withoutsaid' member so that drain pipe 27 extends downward'at the outer side of the furnace. lt'flwill be notedthatldrain pipe 25 as shown in Figs. 1 and (Sims a decided inclination downwardly; .Liquid is supplied to the nozzle 11 of the humidifying unit by a pipe 34 which may be con-. trolled by an electrically controlled valve 35. Valve 35- is'controlled by a'thermostat36 shown as projecting through casing 30 and. secured therein and projectinginto chamber 30a. Valve 35 is-shown as connected to thermostat '36 by wires or conductors 37. Valve 35 can also be controlled by a thermostat or humidistat in the rooms to be humidified or heated, or controlled to operate synchronously with an oil or gas burner. The water before passing through valve preferably passes through a strainer 340: also disposed in the supply line 34.

In Figs. 6 and 7 an air conditioning a-pparatus in the form. known as the Plenum system is shown. This apparatus comprises a casing 38 being rectangular in form at one end and having an outlet conduit 39 leading to a fan casing 40. Said casing has a contracted inlet 38a and has disposed therein a seriesfof radiators 41. The humidifying unit shown in Fig. 1 is illustrated as supported by casing 38 and dependingtherefrom. For this purpose casing 38 is provided with an opening in its top between outlet 39 and the radiators 41 and flange 10b of member 10 rests ontop of casing38- and is secured thereto by screws passing through the holes 100. The portion of the unit be-- low flange b depends into the casing 38. ater is supplied to the humiditying unit and the nozzle 11 thereof by a' pipe 42controlled by an electrically operated valve 43, a strainer 44 also being disposed in the pipe 42 which pipe is shown as passing through one of the coils of one of the radiators 41. Valve 43 is shown as connected by the wires 45 to a thermostat 46 disposed in the casing 38 and projecting through the wall thereof. The member of the unit drains into the T 26 as previously described, from which a pipe a extends through the front of casing 38 where it is connected to a T 26a to which a downwardly extending drain pipe 27a is connected.

In operation, when the device is used ina furnace as shown in Figs. 5 and 6, water will be supplied through pipe 34 controlled by valve 35. The water will be carefully strained of all sediment or solid matter in member 340. Valve 85 will be regulated by thermostat 36 or it may be regulated to operate synchronously with an oil or gas burner. As stated, valve 85 will also prob-. ably be under the control of a humidistat in the rooms to be heated. If moisture is desired in said rooms and the temperature in chamber a is suflicient, valve will open so that fluid will be delivered under pressure to nozzle 11 and will be projected in fine mist or spray longitudinally of the unit in the general direction of the axis of members 10, 17 and 20. The spray diverges from nozzle l1 and as it moves lengthwise of the unit it will impinge somewhaton member 14 and the impingement on the members. 17 will increase as the spray passeslengthwise of the unit, owing to the converging arrangement of the conical surfaces of members 17. The hot air passing through chamber 30a will pass through the openings between members 10, 14, 17 and 20 and some ofthe moisture will be carried by this air to the outer side of the unit and will be evapo rated by and carried along with the air through the conduits 32 andsupplied to the The members 14. 17 and 20 will be heated substantially to the temperature in the chamber 30a and as the mist strikes these plates, there will be a considerable clegree of evaporation of the moisture and this evaporated moisture will also be taken up by the air and will pass with the air through the conduits 32. Should any or" the moisture impinglng on the members 17 accumulate thereon it will drain downwardly and inwardly onto the next members below and if any moisture collects in member 20, it will drain out through opening 20a to the pipe 25 and thence through drain pipe 27. The member 28 is provided so that pipes 25, 24 and the T 23 can be readily In the modification shown in Figs. 6v and 7 the action of theunit will be substantially the same and the air passed through the apparatus will largely pass through the unit and carry the moisture therefrom to the rooms to be'heated. In said apparatus the air before taking up the'moisture will pass through the radiator 41 and will be located so as to readily take up moisture; The valve 43 in the showing in Figs. 6 and 7 iscontrolled by thermostat v46 'as well as by a humidistat in the rooms to be treated, so'that the water will not be turned on if the temperature in casing 3 8 is not suflicient to properly evaporate it.

or strained in member 44. In all operations otthe unit any moisture collecting in member 10 will drip from edge 10d.

'Fromthe above description it. is seen that applicant has provided a simple,- very compact. and highly 'efiicient humidiiying unit. The same takes'up comparatively little space and it is simply made and very easily assembled. The members 14, 17 and 20 well as the spacers 19 will preferably be made of copper or' other, ,non-rustablemetal. Member 10 prefe'rablywill be made as 'a casting. The device is easilyinstalled in a furnace or air treating apparatus as shown and can be placed in any air duct, or if 1 desired, in a room to be humidified where it can be usedm connection with a radiator.

- The device has been amply demonstrated in actual practice and found to be very success: fuL- A large proportion of the water delivered by nozzle 11 is evaporated so that an ample supply of humidified air is assured I It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists of a device capable of carrying out the objectsabove set forth, in the parts and combinations'of' parts disclosed and defined in the appended claims.
